What are the reasons and solutions for Christmas cactus not blooming?
Christmas cactus (Schlumbergera) is a plant that is both attractive and said to protect against radiation, and many people like to keep it at home. Many people do not even know that Christmas cactus can bloom, because they have never seen it flower. So why does Christmas cactus not bloom? Let's take a look together.
1. The time has not come
One of the simplest reasons why Christmas cactus does not bloom is that the time has not come, and "the time has not come" has two meanings: first, the growth time has not reached the requirement for blooming; second, it is not in the flowering period. The specific solutions differ accordingly.
Solution: The flowering period of Christmas cactus generally begins with buds forming in October-November, blooming starts in February of the following year, and the flowers begin to fade in early April. If it is not within this time, it is normal for Christmas cactus not to bloom. Christmas cactus is generally propagated by cuttings and grafting, and both require 2-3 years of growth before it can bloom, so no matter how good the care is, if it has not grown enough, it will not bloom.
2. Improper lighting
The growth, development and flowering of any plant cannot be separated from sunlight, and Christmas cactus is the same, needing light for photosynthesis. If the light is insufficient, it will be unable to bloom normally. However, the light that Christmas cactus needs is not abundant light, but short light. For Christmas cactus, short-day conditions are what allow it to produce better flowers, and if the light period is too long, it may also fail to bloom.
Solution: Christmas cactus differentiates flower buds when it blooms in autumn, and at this time ensuring short-day conditions is what helps it bloom. At this stage, Christmas cactus needs more than 12 hours of darkness each day, and at night it is best to place it somewhere without lamplight, so that normal blooming can be ensured.
3. Temperature too high
Christmas cactus also needs a suitable temperature to bloom, with the optimal growth temperature being 16-24 degrees. If the daytime temperature is too high or the nighttime temperature is too low, then it will also affect the blooming of Christmas cactus. In addition, it should be noted that there needs to be a certain day-night temperature difference between day and night, so that its flower bud differentiation can be effectively promoted.
Solution: It is recommended to keep the daytime temperature at 20 degrees, with a temperature difference of about 5-10 degrees at night compared with daytime, so that it is beneficial to its blooming.
4. Insufficient nutrients
The blooming of Christmas cactus requires a certain supply of nutrients. Although the demand is not great, insufficient nutrients will affect blooming, resulting in small flowers or even flower failure.
Solution: Before flowering and bud formation, apply cake fertilizer water once every 10 days, or apply a phosphorus and potassium fertilizer once; either is fine. However, be careful not to apply nitrogen fertilizer, so as to avoid excessive growth of branches and leaves and failure to bloom.
